Bo discovered that the Fae families were being attacked by a Cherufe which the Noble Fae families had double crossed, Hale's father being one of them. Bo stopped the attack and announced the coming of the Garuda to the assembled families, but none of them wanted to help her. Bo told them all that it was obvious to her that the Garuda was making them all more violent towards each other than they normally were and they needed to band together to fight it, but they were too frightened to do so. This left the fate of the Fae in the hands of Bo and her friends.

In Fae-nted Love, Bo was still with Ryan as the episode began. Bo fed from Ryan after she was injured and then afterwards tried once more to leave him.

In Lachlan's Gambit Trick was attacked by a gang of Berserkers sent by The Garuda, but they were repelled by Bo, Hale and Ciara.

When Bo and Hale arrived, they learned that although The Ash was dead, his venom was taken by Lauren and they have a slim chance to win. Kenzi rescued Dyson and Bo finally accepted that she was the one to face The Garuda to save the lives of her friends and everyone else.

During Into the Dark Bo attended a wake for Ciara at the Dal Riata. Trick then revealed that he isn't Bo's father, but rather her grandfather and that Aife was his daughter. Trick also told her he doesn't know who Bo's father was. Trick explained that Bo's blood had the power to enslave others, like her mother did, and that using that power might turn Bo to the dark side. Bo asked that Trick call the Nain Rouge to get some answers, but he could not. Bo cried out in anger and the Nain Rouge then appeared to her. The Nain Rouge told Bo that Dyson misunderstood what the Wolf Spirit told him and the way to defeat the Garuda was to join the Light and Dark Fae into a single force. Bo and Lauren attend the funeral of Lachlan, and find The Morrigan there. Bo asked for Vex's help, but was told that Vex would remain in the dungeons forever because he took control of The Morrigan's body and humiliated her. However if Bo retrieves an item for The Morrigan she would give Vex to Bo. Bo located the item and brought it to The Morrigan. After Vex was placed in Bo's care, a group of Red Caps attack and take Vex with them. After Bo confronted them, she was forced to steal the item from The Morrigan and bring it to them. Bo seduced The Morrigan and used her powers to control her long enough to steal the item back. Bo gave the item to the Red Caps, but The Morrigan stopped the transaction and moved to kill everyone. Vex helped Bo to overcome her, and Vex agreed to help Bo in the coming battle with The Garuda. Bo then gathered her friends and offers a plan that might win them the battle.

During Flesh and Blood, the Second Season finale, Bo met with Trick and he told her of his concerns about her plan to fight The Garuda. He gave Bo a vial of life essence to protect herself in the event she felt herself slipping towards the dark side. Lauren gave Bo the remaining venom she had saved from Lachlan, enough for one dose, and told Bo that she was what they needed, a leader, and Bo took that to heart in her plan against The Garuda. Bo explained that her solution to The Garuda's power was for her to enslave her friends with her blood in order to remove all strife between them. Lauren injected Bo's blood into everyone, but Vex managed to avoid being injected. Bo and the others then find The Garuda and after several battles, find The Garuda and Trick. Dyson and Bo arrived as Trick was about to rewrite the Laws under the sway of The Garuda's powers. Dyson attacked The Garuda, but was severely injured. Bo then confronted it and the two battled. Vex's trickery was revealed and he was injected which added to Bo's powers. The Garuda then entered Trick's body and attempted to use Trick's body to rewrite reality, but Vex delayed this with his powers. Bo used the venom on Trick's body and killed The Garuda, but in doing so, also killed Trick. Bo began to slip away into darkness and insanity, but not before she gave the life essence to Trick which saves him. Bo continued to turn dark, but Kenzi unbound everyone from Bo and stops it from continuing. In the aftermath, Bo seemed to still be under the effects of the dark that was growing within her.

At the end of the Second Season, more of Bo's history was revealed, including that Trick was Bo's Grandfather. Bo defeated several threats to the Fae, including The Garuda, but at a high cost which included the deaths of Nadia and Ciara.

It was unclear as to who The Wander was, their relationship with Bo and what Bo's continuing changes following her Dawning would result in. Bo and Lauren's relationship was uncertain as was Bo's relationships with Dyson and Tamsin.

Fourth Season

Bo's first appearance in the Fourth Season was in the premiere episode In Memoriam where she appeared for only an instant at the very end of the episode. She seemed to be waking up, gasping for breath, and her eyes were glowing a bright blue. No other details of her location or situation where given.

She next appeared in Sleeping Beauty School where she found herself on a old train that seemed to be traveling through an infinite darkness, her memories seemingly unclear though she did remember Kenzi's name. Freeing herself from her captivity, she opened a door which led out of the train and jumped into the darkness, her fate unknown at that time.

She next appeared in Lovers. Apart. finding herself after escaping the train in a cottage deep in the woods. She was discovered there by a family who were the victims of an ongoing curse where each generation of the family were possessed by what they called a ghost and forced to kill the other members of their family. Bo came into contact with the ghost, which turned out to be an Elemental, absorbing her into her body to protect the family. In doing so, Bo learned that the Elemental was seeking revenge for the death of her love and taking out that revenge on the family. With the help of Dyson the Elemental was reunited with her love and the curse was ended. Cleo, who arrived with Dyson in search of Bo, attempted to take her to Vex as part of a deal Cleo made with him. Bo overcame Cleo and then left with Dyson to be reunited with her friends and family.

After returning home in Turn to Stone, Bo was shocked to discover that Kenzi had been hiding secrets from her and Lauren was using a false name and was a fugitive. She also had to deal with Tamsin coming into her full power, the threat of Massimo and as well, having to face being told she was Dark Fae by the Una Mens.

During Let the Dark Times Roll, Bo went to find answers for what the Una Mens had revealed to her from Vex, but found that The Morrigan had taken back control. Bo attempted to find a means of getting out of the agreement she had apparently made, declaring herself as Dark Fae, but with little success. Following her being reunited with Lauren through the actions of The Morrigan, she searched for Vex and found him. However he did not have any answers for her and Bo was unable to stop Vex from cutting off one of his hands in order to escape the Una Mens. Confronting The Morrigan again, Bo was shown a pledge she signed with another Dark Fae named Rainer, who likely was Bo's father The Wanderer. Unable to locate him at the time, Bo was forced into being under the control of The Morrigan, though she did not accept that. Following this, Lauren revealed that she had joined the Dark Fae which harmed Bo's relationship with her. Bo also learned that Trick had been named The New Acting Ash by the Una Mens which officially put her at odds with Trick, but unofficially she remained close to him as family was more important than Fae politics.

During Of All the Gin Joints, Bo was contacted by a singer that claimed she knew Bo even though Bo did not know her. When Bo heard her sing, blocked memories that Bo had surfaced about her time on the Death Train, but they were vague and unclear. As well, Bo's sexual needs seemed to become more dominant and violent as was seen when she was with Dyson. Bo tells Dyson that she has been forced to join the Dark. Trick warns Bo and Dyson that they cannot be together as Light and Dark are forbidden to do so. Bo discovers that she is marked by The Wanderer for unknown purposes as well. Bo and Dyson are then found together by the Una Mens who proclaim that Dyson has broken the laws and move to attack him as this episode ends, but the reason is unknown.

In La Fae Époque, Bo entered Dyson's memories with Lauren monitoring her and Cassie, an Oracle Fae whom Bo encountered in Dead Lucky, making this possible. Bo experiences Dyson's memories of Paris in the 1890s, placing herself within Dyson's actions there. She feels and acts as Dyson did, having little control over what happens to her there. In doing so, Bo experiences Dyson's first encounter with Trick, Dyson coming into possession of what are called Helskór or hell shoes, the death of Flora, a Fae that Dyson knew at that time, and Dyson's first encounter with the Una Mens. Upon Lauren's actions in helping Bo to escape Dyson's memories, Bo then recovered one of the Helskór and used it as a bargaining chip with the Una Mens to force them to release Dyson. Kenzi and Hale. At the end of the episode, Bo decides to take events into her own hands, recover the missing Helskór and use it to confront The Wanderer with the help of her friends.

During Groundhog Fae, Bo found herself trapped within a time loop were she experienced the same evening over and over again. Eventually she discovered that she was trapped along with Tamsin and Hale in the loop who were aware of its existence. During the course of the loop. Bo was intimate with Tamsin at one point. She also confronted Trick over why he was not helping her to find The Wanderer and he revealed to Bo that he was frightened. Bo and the others escaped the loop, but in order to save Tamsin and Bruce, Bo was forced to confront Krampus who forced Bo to admit her fears to him. Bo revealed that her greatest fears were that she would lose her family and friends again, but also that she feared what she could become at the hands of The Wanderer. At the end of the episode, Kenzi gave Bo a package which was addressed to Bo in Bo's own handwriting. The package contained a sealed container of the black smoke which previously had been used to take Bo to The Wanderer.

Destiny's Child marked an important moment in the Wanderer arc for Bo. During this episode Bo came to the conclusion that she needed to confront The Wanderer and find the answers she was seeking. Opening the container of black smoke, Bo discovered that it was a servant of The Wanderer who was willing to take Bo to The Wanderer for a price. Bo agreed to this and left with him, but soon found that it was a trap. Bo managed to escape by falling into Irkalla, otherwise known as Hell. To escape from Irkalla, Bo answered a riddle from Leviathan, the ruler of Irkalla and asked her a riddle which could not be answered. Before she was freed, Leviathan told Bo that they would meet again as soon someone that Bo loved would die. Upon returning, Bo overcame the servants of The Wanderer with the help of Dyson and Lauren and then left with them to confront The Wanderer. Bo returned to the Death Train and battled with The Wanderer, now known as Rainer, for a short time. Rainer then touched Bo over the mark he placed on her and she touched him which caused Bo to seemingly come under Rainer's control. Bo then returned to the Dal Riata where Trick, Dyson and Lauren were waiting for her. She explained that becoming Dark was her idea so that she would return to the train willingly and break the curse that held Rainer on the train. Rainer then appeared and stood next to Bo, the two holding hands as Bo declared that Rainer was not her father, nor her enemy but was, in fact, her "destiny".

During Waves the events which occurred on the Death Train when Bo first met Rainer, The Wanderer were revealed. At their first meeting, Bo and Rainer were at odds, but over time Bo seemed to become smitten with him. Eventually Bo came up with a plan which would result in her returning to the Train and freeing Rainer, placing clues with Rainer's help which she would find. As a final means to force Bo to return to the Train, she also had Rainer witness her pledging herself to the Dark Fae. It was also shown in this episode that Bo had severed her ties with her friends and had Rainer move in with her. Bo also confronted the Una Mens with Rainer at her side and with his ability to foretell the attacks of the Una Mens, Bo was able to defeat them easily. At the end of the episode, Trick approached Bo and begged her not to kill the Una Mens, but was too late to prevent this from happening.

In End of a Line, Bo was attacked by a zombie and all evidence indicated that The Wanderer had sent it after Bo. With Dyson, Tamsin and her mentor Acacia's help, this was proven to be incorrect. Bo did come to blows with Acacia and was forced to drink the blood of the head zombie in order to stop their attacks. In the aftermath, Dyson confronted Bo over her relationship with Rainer, but when Bo could got answer his questions, Dyson seemed to end their personal relationship. When Tamsin saw an image of Rainer, she told Bo that Rainer was not the one that had hired her to find Bo. Kenzi revealed to Bo that Hale had given her a ring and they intended to marry, but upon her return Bo found Kenzi injured and Hale murdered by Massimo. Kenzi demanded that Bo revive Hale as she had previously done for Dyson[8] but Bo refused as it would have killed Kenzi. Bo was forced to use her powers to calm Kenzi, but not before Kenzi told Bo she would never forgive her for not saving Hale. At the end of the episode, Bo was kneeling beside Kenzi and Hale unable to do anything.

Origin marked major changes in Bo's life. She attended the burial of Hale with Kenzi, Dyson and Tamsin and could not bring any resolution to Kenzi's pain in losing Hale. Having promised Kenzi that Massimo would pay for killing Hale, Bo was unable to do so which would have consequences. Bo was approached by a knight who called her "Queen" and when Rainer appeared, called him "King." Bo then learned that Rainer would live for only seven days upon returning to the Earth as per prophecy, six days having passed by this episode's timeframe. The knight assisted Bo and Rainer in an attempt to find a solution in order to save Rainer and in the end, the only means to do so was for Bo to marry Rainer. Bo asked Dyson for his advice, but he refused to do so. Tamsin revealed to Bo the meaning of a crest that was found with items that Hale had bequeathed to Dyson and in doing so, Dyson told Bo that prophecy said that she was "The One" but not what that meant exactly. Bo met with Lauren who attempted to reveal to Bo what she had learned about Rainer, but Bo would not accept that information, instead believing that Lauren was trying to break Bo's relationship with Rainer. As a result, Bo's relationship with Lauren seemed to come to an end or at least was part of the reason why Lauren soon after attacked The Morrigan. Bo was confronted by Kenzi over her not helping Kenzi in her quest to find revenge. Kenzi then demanded that Bo unclaim her, and Bo did so, which severed their relationship, Kenzi leaving soon after. Bo then married Rainer with the goal of saving his life and braking his curse. It was then revealed that in doing so, both Bo and Rainer had completed a prophecy that the knight was secretly trying to make unfold. This meant that with their marriage that a being called The Priapus was released. At the end of this episode, the mark which both Bo and Rainer shared began to glow brightly, the meaning of this not being made clear other than it was connected to the release of The Priapus.

In the season finale Dark Horse, Dyson expressed his love to Bo and formally gave fealty to her, saying that he was meant to serve a Queen, not a King. When the portal that Bo's Father was intending to use to arrive on Earth was found, Bo attempted to defeat a group of Remnants, but in doing so was turned towards her dark side. She declared that her father intended that she become the Dark Queen and threatened Dyson, but he was able to break the change and save Bo from changing fully. Bo then asked Dyson, along with Tamsin and Trick, to defend against the oncoming hordes of Remnants. Bo then left to confront Massimo and killed him, saving Lauren and in the process almost causing the death of The Morrigan when Bo used her to gain the upper hand on Massimo. When Bo returned to join in the battle against her father, she was witness to Kenzi sacrificing herself in order to close the portal, Kenzi figuring out that the prophecy about Bo's heart referred to her and she needed to sacrifice herself to save the world. Following Kenzi's death, Bo was seen at Kenzi's grave promising that she would find a way to bring Kenzi back. Bo also declared that she was not going to be afraid of anyone, or anything, ever again.

At the end of the Fourth Season, Bo was facing a future without Kenzi and how that would change her going forwards was unclear. Bo appeared to be determined to bring Kenzi back at any cost. The question of what her father wanted with her was still not revealed, but it was told in passing that Bo's "destiny" was to be the Dark Queen as part of that plan.

Fifth Season

Bo made her first appearance in the Fifth Season premiere episode Like Hell, Part I where she recovered the Helskor and traveled to Valhalla in an effort to find Kenzi and return her home. After meeting Freyja, Bo located Kenzi and reunited with her. When Kenzi found out that Hale was coming to marry her, Bo became Kenzi's Maid of Honor for the ceremony. However, it was revealed that this was all part of Bo's Father's plan to bring Bo to him and Bo was sent to her Father's realm by Freyja.

In Like Hell, Part II, Bo arrived in her Father’s realm and encountered her Stepmother, Persephone, who was the wife of Hades. Through her Bo found out that she was born in Hel, and some of the truths about her mother Aife. Bo confronted her Father, but after a brief shadowy encounter, escaped to the Gates where Dyson helped her return to Earth. At the end of the episode, Kenzi told Bo that she needed to leave, and a gift from Hale allowed her to leave for Spain, leaving Bo and the Fae behind. Bo then lit Persephone’s candle which she brought to Earth with her, which seemed to draw to Earth a dark spirit that possessed someone elsewhere.

During Big in Japan, Bo and Tamsin encountered a Fae hero who asked for their help as he was being targeted for assassination before he could ascend to the head of his family, becoming a God. After some effort, Bo discovers that his sister was trying to stop his ascension because he held a lie about his past which would doom him. Bo and Tamsin stopped the event and the truth was revealed that the real hero was his sister all along. Bo attempted to feed from Dyson, Tamsin and Lauren at several points in the episode, but found she could not, being repelled each time she tried and her sex drive doesn’t exist. After meeting with Trick, Bo found out that her mother, Aife suffered a similar problem for a year before her sex drive returned. Bo was attacked by the now disgraced hero and suffered a severe wound. Lauren operated on Bo, but she still needed to feed to heal, but remained unable to do so. Bo then revealed that she didn't want to live because she believed that she would be alone eventually as one by one everyone would leave her just like Kenzi and so many others have done. Tamsin, Dyson and Lauren told Bo she would never be alone, and she regained her ability to feed once more, feeding from Dyson, and healing herself. Confronting the once hero afterwards, when he tells Bo that she has no idea what being the Chosen One means, she replies: "It's bullshit." as she walks away. At the end of the episode, Bo, Lauren, Tamsin and Dyson were together for a movie night, their relationships strengthened once more.

In When God Opens a Window..., A runaway asked Bo for help at first, but stole from Bo. When he was confronted, the runaway revealed that he was being hunted, and the hunter held the runaway responsible for the death of his wife and child. Bo was struck by an arrow which contained something Lauren called "Fae Kryptonite" which interfered with Bo's ability to heal and she could not do so until all of the substance was removed from her wound, Tamsin then allowed Bo to feed from her and heal. From the beginning, Bo felt that there was something about the runaway, named Mark, that was familiar, and by the end of the episode it was revealed that Mark was in fact Dyson's son through a previous relationship. However, before this was revealed, Bo became intimate with Mark at least once during the episode, though this apparently never was realized by Dyson. Bo's relationship with Tamsin was strained at several points during the episode, the two arguing over methods and actions, but eventually came to terms with working together. Bo also made Tamsin swear she would never reveal to Dyson that she had been intimate with Mark, his son. Dyson did reconfirm his love for Bo at the end of the episode and she told him that she would be there for him if he wanted her.

During It's Your Lucky Fae, Cassie the Oracle turned up missing as Bo received a gift from her father on her birthday and needed help in understanding what it was. To find out what happened to Cassie, Bo joined a Fae dating site and met the last person that Cassie went out with. Tamsin and Lauren bought Bo a stuffed cat for a birthday present which possessed Bo with the powers of a cat and began to turn her into one. Using her new found powers, Bo found Cassie and two other Oracles who had been imprisoned and their eyes taken from them, eventually revealed that the Oracles took their own eyes out to stop being forced to see all of time. Dyson discovered that during her investigation Bo went on a date with one of the dead from the elevator crash which gave the first clue that something was happening and at the end of the episode, one of the possessed elevator bodies had Trick’s ledger of Fae names and found out who Bo was. Bo did not uncover what her father’s gift was, but at the end of the episode, Bo and Tamsin have an intimate moment together which seems to draw them closer in their relationship than simply roommates.

In Clear Eyes, Fae Hearts, Dyson asked Bo and Tamsin to go undercover at a High School to help investigate the Fae cult he has been tracking which seemed to be connected to the death of a football player, Bo as a cheerleading coach and Tamsin as a cheerleader. Bo discovered that the three possessed humans were found to be behind the death and fed upon the emotions of the crowd at the football game for an unknown purpose, but Bo failed to stop their plan and suffered an injury that did not heal when she fed on Tamsin. Trick came to the conclusion that the three humans were possessed by Ancients, who Trick described as being the most powerful of Fae during a meeting he held with Dyson, Bo, Lauren and Tamsin.

During Here Comes the Night, a tornado created by the Ancients, smashed through the city, doing massive damage and destruction, Bo helping as she was able to. Evony’s doomsday device ran out of power and a creature was released which was invisible. Bo and Lauren confronted Evony who revealed that at one time she dated the god Eros, who she trapped in the device with Vex’s help. Evony, Bo and Lauren confronted Eros and he was killed by lightning, seemingly by Zeus. After giving visions to all those that had Bo's blood in them, the Oracles gave Bo visions of those she loved trying to find Bo’s truth, but Trick interrupted them. Bo revealed her father was Hades to Trick and that she was born in Hel. Tamsin confessed her love to Bo, but Bo told Tamsin she did not love her the same way. At the end of the episode, Bo blew out Persephone’s candle, but it relit afterwards.

In End of Faes, Bo was invited to a party being held by the Ancients in her honour. Bo confronted Zee who offered Bo freedom from her father and to stop Hades from using her to end the world. Zee had Bo take a sip of the drink of prophesy and Bo sees s future which seems to show her father destroying the world and Bo agreed to help Zee stop Hades. Later Bo realized that the vision was Iris ending life and not her father. Bo searched for a way to stop Iris and Trick told Bo of a mysterious box that could contain evil which Bo realized was the birthday gift her father sent her. Zee and Bo fought over the box until Bo gained control of it. Zee warned Bo not to open the Box but Bo recalled this vision of her father, who gave Vo riddles, and then Bo decided to open the box which opened with a flash of light as the episode ended.

In 44 Minutes to Save the World, Hades was released from his prison and walked the Earth and when he visits Lauren’s clinic is revealed to be Bo’s Father to both Dyson and Lauren by Bo. He also reveals that his mark is on both Bo and Mark, protecting them from harm. Nix goes to Dyson’s gym where Alicia is, but before she can be harmed, Hades and Bo manage to stop Nix by trapping her in the jack-in-the-box. Afterwards, Hades is imprisoned, and Bo confronts Hades for forcing Kenzi to close the portal, the two arguing over Bo’s past. Hades claims that all that Aife told Bo was false but Bo refuses to believe him. Bo and Lauren express their love for each other, but Lauren is stuck by a car, seemingly fatally. When Bo approaches Lauren to help, Lauren seems to feed like a succubus on Bo.

During Like Father, Like Daughter, it was revealed that Lauren survived her accident, Bo assuming that she saved Lauren while Lauren was not so sure. Kenzi returned, asking for Bo’s help to find a special painting from her estate which might be capable of removing the Ancients. Kenzi joined up with Bo to investigate an art house auction where the painting was being held. Bo stole the painting and encountered Persephone as a result. Bo confronted her, but Bo released Persephone in exchange for her knowledge about the painting. Bo, Kenzi and Trick then discovered that the painting held a song which could banish the Ancients. Bo then asked Persephone to help banish Zee but Persephone double crossed Bo. However, Lauren took the powers of a Siren, sang the song and seemed to banish Zee from Earth which revealed what Lauren was capable of. Lauren and Bo then discussed their future, Lauren unsure of what her changes meant. Kenzi warns Bo not to trust her father and this leaves Bo to consider her next moves with regards to her father, even as she is unsure why she did not use the painting to banish Hades as well.

In Sweet Valkyrie High, Bo was present when Evony demanded that Lauren make her Fae once again. Later, when it was revealed that Evony was suffering from a fatal medical condition, Bo attempted to comfort her, then joined Lauren to take Evony to see Hades in an attempt to save her, but he refused to do so. Evony eventually puts her faith in Lauren, who promises not to give up on her, and Bo, Lauren and Evony’s relationship became more of a friendship. After finding out the truth about what Hades’ plans were, Tamsin met with Bo, the two mending their relationship and Tamsin settling for being friends. Tamsin then warned Bo that her father is building an army and the two then attempted to come to a plan to deal with Hades.

During Judgement Fae, Lauren revealed to Bo that Hades helped her become a Conduit which brought stress to their relationship. Bo then discovered that Zee had not been banished and then confronted Hades who revealed what he did. Bo then encountered Zee, but discovers it was actually Elizabeth, her human host, and she did not know where Zee had gone. To discover what Zee was doing, Bo was forced to act as a lawyer in a courtroom in order to see Hephaestus and eventually passed the test when she answered her own truth. While in Hephaestus’ armoury, she encountered Zee who had possessed Lauren’s body and with her Hera as well. Zee left Lauren’s body after sending a message to Bo, returning to Elizabeth’s and after warning Bo about Hades, banished herself and Hera from Earth. Bo receives a weapon, a horseshoe, to be used against Hades but does not know what to do with it. Lauren then takes an antidote, ending her being a Conduit, and admitted to Bo that she lost herself in what she became. Lauren then breaks off their relationship, claiming that her being human and Bo being Fae made it impossible and she wouldn't allow Bo to suffer when she passed on. Bo confronted Hades, blaming him for all that had transpired, but he claimed that he only wanted Bo to be happy, which she does not believe, Hades then claiming to step back from their relationship and Bo warning that she would never follow him. Bo then encounters Dyson, the two talking about love and Bo wondering if she is meant to have love. Bo then is seen becoming intimate with Tamsin, but as they kissed, Bo’s hair turned white, her features shifted and her appearance became similar to that of Hades.

In Family Portrait, Bo learned that Aife, her mother, had been held in a Fae institution since attacking Trick at the beginning of Season Four, which enraged Bo as that was not revealed to her. After Hades left his isolation cell, Bo discovered that Aife and Hades were at Zee’s condominium, seemly together again as a couple. They explained that everything Bo had been told was a lie and they tell Bo her past from their perspective. Hades tells Bo that like her, they want justice and want Bo to join them, but she refuses. Afterwards, Aife encountered Bo and claimed to be lying to Hades and when Aife claimed that Bo had a plan to overcome Hades, and Bo told her this is wasn't true, Aife lost her mind once more. Bo confronted Trick over Aife’s being imprisoned and he told Bo that Hades used Aife for his own ends, Trick giving Bo all of the information on her mother, telling her to make up her own mind about what her life’s story really was. Tamsin and Lauren joined Bo in reviewing Aife’s past, and the tapes revealed an video of Bo seeing her mother. This revealed that Hades had been impersonating Bo, explaining what happened between Bo and Tamsin in the previous episode. Bo, Tamsin and Dyson attacked Hades at the condominium, but had no effect on him. Bo then attempted to remove Hades’ mark from her chest, but it remained. Bo then returned to the condominium where she finds Aife dead and Trick close to death, Trick dying moments after Bo arrives. When Dyson finds Bo soon after, he finds her catatonic, kneeling beside Trick and Aife’s bodies, and not responsive.

During Follow the Yellow Trick Road, Bo found herself in a world of grey, she being the only colour while in the real world, Bo was actually in a coma. Bo follows a path, like Dorthy from the Wizard of Oz in which she encountered all of her friends, one by one, as she looked to see the Maestro. Bo encountered Tamsin, Dyson, Lauren and Vex before finding the Maestro which turned out to be herself and she told herself that she must be the master of herself. Bo was in her coma because of a Fae moth that fed on suffering. Bo encounters Kenzi in her dreamworld who was the moth in disguise and after overcoming her fear, was told by the moth that she has the key to overcome her father, that being the horseshoe that Bo possessed. Bo was then brought out of her coma by Lauren who had found the answer by reading books that Mark and Vex brought from Trick’s library. Bo came out of her coma to find all of her friends with her, Bo crying that Trick was gone. Bo then read Trick’s will and finds that he left gifts to all of his friends, Dyson and Mark received ownership of the Dal Riata, while Trick's gift to Bo was telling of his joy and love for her.

In Let Them Burn, Kenzi and Bo found Vex critically injured and Tamsin missing. Vex survived, but could not speak as his vocal cords were damaged, but Vex gives them a message that Bo’s midwife is alive and they need to see Evony to learn more. Bo and Kenzi learned that Evony had Bo’s midwife and she was at a Fae horse ranch. Bo and Kenzi went to the horse ranch and Lou Ann confirmed that Trick was the one that rescued her. When Bo asks about the Pyrippus, Lou Ann took Bo and Kenzi to a stallion on the ranch. Bo calmed the stallion, then discovered that the horseshoe did not fit. Bo then realized that Hades was trying to control and make her submit in the same way that Lou Ann was trying to control the stallion. When Bo realized this, she made the connection that she was the Pyrippus. Bo then decided to face Hades, to give him what he wanted from her, that of Bo surrendering to him, submitting to him, in an attempt to stop him. Bo goes to Hades, and finds Tamsin there, imprisoned. Bo tells Hades she came to him because she wanted to and that he should release Tamsin, however Hades will not and reveals that Valkyrie die in childbirth and that is the fate of Tamsin. Bo then told Hades she will side with him, but Hades demands that Bo kill her remaining friends to prove that she is his. Bo then poured gasoline over her home, called Kenzi, Lauren, Dyson and Mark there who were then trapped in the fire that Bo set to the approval of Hades. Hades then shows Bo a throne, having her take her place there before activating his mark on Bo's chest, seeming to cement his control over her by doing so and thus turning Bo fully into the Pyrippus.

In the series finale Rise, Hades revealed he wanted Bo to feed off all Chi in the world. Hades then used the Hellskor shoes to trap Bo and forced her to do so, telling Bo that the bringer of death was what she was meant to be. Bo feel to his attack as Hades used all of the things that had gone wrong for Bo in her life to break her. He also told Bo that she could not love, which pushed Bo over the edge. Bo then fed on the city’s Chi, killing all those she fed on, Hades then turning them into the army that he desired. None of Bo’s friends were effected because of the horseshoe which Bo left in their care when she set the clubhouse on fire which protects them from harm. Hades demands Bo retrieve the horseshoe in order to end their threat and complete his plan. Bo confronted her friends, their attempt to bring her back failing, Bo destroyed the horseshoe, then began to feed on her friends. Bo relived her life through the memories of them through their Chi and this broke Hades’ control over her. Bo confronted Hades, she overcoming him with the love of her family, banishing him and then returned the Chi she took from the city, ending Hades’ threat. During the battle, Tamsin gave birth to a baby girl, named Dagny, asking Bo to look after her daughter. Bo promised to do so before Tamsin passed away, Tamsin turning into white light and vanishing into the sky. Bo then gave Tamsin’s baby to Kenzi who leaves, promising to look after Dagny and be there for Bo always. Bo and Lauren renewed their relationship for as long as Lauren would live. Dyson decides to wait to continue his relationship with Bo otherwise. Time passes and Dagny was brought to the Dal Riata, meeting her Family, and her sister Bo. The series concludes with Bo promising that they will be ready for the day Hades returns seeking Dagny.

Powers and Abilities

Bo is a Succubus and has the power to absorb the life force, or Chi, of humans or Fae by drawing it out through their mouths and also through sexual encounters. Through this feeding she sustains her life and in addition can use the absorbed Chi to heal wounds she may have suffered. Bo needs to feed at regular intervals, which can be extended by her will power, but at some point she will have to find prey and feed or she will die.[9] It is possible through the use of drugs, as shown in the series, to help control that need, but it is not a complete cure for it.[10] It is important for Bo to keep control of her needs when feeding because it is easy to take too much energy from her prey and kill them.[11] Over time Bo gained the control needed to not constantly kill her prey, but in the event of her need overcoming her, Bo's control can be easily lost. It has been shown that Bo can feed from Fae without fear of killing them. However, the Fae is drained to the point of near exhaustion when this occurs.[12]

Closeup image of Bo saving Dyson by transferring energy from her to him in the episode (Dis)Members Only

Bo has displayed several powers in the series. First is the ability to control others emotionally and mentally by touching their skin at any point on their body. The outward appearance of this power is the washing of a bright glow of light over the victim’s skin.[13] That is accompanied by the victim being enthralled to accept suggestions by Bo. The second is when Bo is feeding on her prey, the energy taken from them by her appears in a form similar to a white vapor that leaves the mouth of the prey and is then consumed by Bo through her mouth.[14]

Connected to Bo's feeding is an associated ability to transform those she feeds upon into thralls who are completely devoted to her.[15] It Is also possible for Bo to transfer energy back to her prey, or, if needed, to pass their energy into someone on the verge of death to help them to recover.[16]

Bo has demonstrated that she can see the auras of invisible Fae if they have a sexual attraction to someone. [17]

There have been two examples of Bo feeding on the Chi of several people without actually being in contact with them. In the second season episode Death Didn't Become Him, she had been shot and seemed to die or become unconscious. In this case, there was a reddish glow throughout her body and somehow she was able to draw the Chi she needed from a great distance away. She was also able to differentiate enough to not draw the Chi from Lauren who was in the same room.[18] Bo also used this ability to revive Dyson in The Ceremony when she returned with his lifeless body and used the Chi of all of the people in the room with her to save Dyson's life, though in doing so she drained many of them severely.

Bo has displayed skill in using various bladed weapons over the series, but tends to prefer to use a small knife that she carries strapped to her right thigh. She has never been seen using any sort of gun or similar weapon and her skill in doing so is uncertain. Bo appears to have some expertise in hand-to-hand combat which she likely learned from Dyson and from her own experiences after leaving home when she was young.

Bo's real human name is Beth Dennis and she is the adopted daughter of Sam and Mary Dennis.

Bo was not allowed to date by her parents who taught her that sex was evil. As a result, when she killed for the first time, she saw herself as a Devil due to her parents' teachings and ran away from home.

The first person that Bo killed due to her Succubus nature was named Kyle Williams and this happened just after she hit puberty.

Since Kyle's death, his younger sister Mel Williams has been tracking Bo and found her through what Bo did in the events of the premiere episode of the series when she killed a man that was threatening Kenzi's life.

Bo did manage to have a tentative relationship with Ciara before her death.

Bo broke the curse that Lauren's girlfriend Nadia was placed under by the original Ash.

Bo had the power to remove Shaman's curse nails which seemed to be an impossible thing.

Bo has travelled by teleportation at least once.

Bo fought the New Ash, and defeated him, but when she had the chance to kill him, she refused to do so.

The Ash, revealed to be a Naga, asked Bo to the his champion against The Garuda, but Bo initially declined to do so until events overcame her refusal and Bo had no other choice but to agree.

Bo was romantically involved with Ryan, a Loki Dark Fae.

Bo was once trapped with Ryan and fought a Djinn who Bo defeated by becoming the Djinn's Mistress for a time.

When Bo and Ryan had sex, it seemed that Bo's inhibitions were no longer there.

Bo had some life force taken from her by a Serket.

Ryan claimed that there were no rules with him, but he sided with the Dark Fae Serket sisters over Bo.

Bo, as part of an investigation, masqueraded as an English Literature teacher.

Bo never went to her High School Prom.

Bo fought a Cherufe once.

Bo met Hale's family and was not impressed by any of them, though at a later point Hale's sister Val joined Bo's plan to attack The Garuda.

At one point, Kenzi and Bo regularly sparred against each other to improve their sword skills.

Bo did meet Nadia several times, but in each case Nadia was likely under the control of The Garuda.

It appears that Bo can heal major injuries to herself by feeding, including loss of blood and severe cuts and lacerations. It can be assumed that broken bones and other more serious injures will heal as quickly if she feeds.

Bo lost her memories to an Addonc once.

Bo can create thralls similar in nature to those her mother Aife can create, but it is not known what Aife's method of doing so is.

Ryan was once turned into a thrall of Bo's when her blood mixed with his while they were being intimate together.

Trick knew of a means to break Bo's control, but the exact meaning and reasons behind it are unknown.

Bo has admitted to Kenzi that she loves her and Kenzi told Bo the same.

Bo was forced to kill Nadia, Lauren's girlfriend, when Nadia was possessed by The Garuda.

Bo attempted to kill The Garuda twice, failing the first time when her plans where overwhelmed by The Garuda.

It was revealed late in the Second Season that Trick was Bo's Grandfather, Aife was Trick's Daughter and that Bo was, in a way, a Blood Princess as Trick was once the Blood King.

It would appear that Bo remembers something of what she did in the episode Death Didn't Become Him, when she took the Chi from an entire room of Fae, but did not harm Lauren who was there. The only thing that Bo clearly remembers is her rage.

Bo at one point used her powers to control The Morrigan.

At one point Bo had images of The Morrigan that she used for blackmail.

Bo's blood has been used as a means of defence against the powers of The Garuda.

Trick gave Bo a cane sword for her birthday in the episode Masks. The cane was once owned by Trick's wife Isabeau and in the hilt it contained a vial of "life essence" that was Isabeau's.

Bo's healing abilities are provided through the powers of her Grandmother. If this was given naturally or by consuming some life essence in the past is not made clear.

Lauren's opinion is that Bo is stronger than Trick is.

Bo killed The Garuda by injecting the venom taken from Lachlan while it was within Trick's body. This killed both it and Trick, but she was able to use the vial of life essence she had been given to return Trick back to life afterwards.

Bo made the decision to save Trick's life, but this had unforeseen consequences in the future, including the appearance of Bo's father beginning in the Fourth Season.

When Bo was checked into prison, her name was stated as being Bo Dennis.

One of the ongoing gags in the series is about toothbrushes. Bo uses them, or is seen with them often.

According to Dyson, Bo had been feeding cleanly and safely by the beginning of the Third Season.

Bo showed the ability to use a semblance of mind control to alter the thoughts of others towards sexual actions. It seems that she could control more than one person at a time.

Bo never graduated from high school.

Eventually the shots that Bo had been receiving in order to control her needs were no longer working.

Lauren allowed Bo to feed on others, but demanded that Bo not feed from Dyson at one point in the series.

Bo seems to almost become drunk when there is a massive amount of sexual energy or Chi around her.

Bo hates coconut ice cream.

Bo's childhood home was in Grimley County which is famous for its cherries and has a festival celebrating them annually.

Bo's name as given to her by her adoptive human parents was Beth Dennis.

Bo left home about ten years ago at the time of Third Season of the series.

Mary Dennis, Bo's mother, suffers from dementia and Bo's father has passed away.

Based on Bo's comments about Dyson when she was drunk, it appears that Kenzi must have told Bo that she went to The Norn to get Dyson's love back, but she is not aware if Dyson loves her or not. However, there is no clear evidence of this.

Bo promised Kenzi that if anything happened to her, Kenzi would be looked after.

After the Dawning, Bo claims to understand how to control her powers like never before. She also indicates that she feels different.

Bo was voted Camp Chipewa's most popular counsellor three years in a row in the past.

Apparently, Bo and Kenzi have not done any private human investigations for some time, probably since the end of the first season.

Apparently Bo does not wear underwear.

Aife claims that Bo is the strongest Fae there is.

Aife confirmed that Bo was named for Aife's mother, Isabeau.

According to the Una Mens, Bo's blood marked her as Dark Fae in spite of her not choosing a side.

Apparently eunuchs are not effected by Bo's Succubus powers.

Bo has admitted her greatest fears are of losing her friends and family and what The Wanderer might change her into.

With Rainer's help in telegraphing the moves of the Una Mens and also telling Bo how and when to strike, Bo was able to overcome the Una Mens and kill all of them.

Bo represents The Dark Queen whom her father wishes to come into full force so he can return to the Earth from Hel. It is possible that if Bo turned completely into the Dark Queen, she would then become the Queen of Hel.

Bo stated that she was on a "feeding spree" for ten years before she was helped by her friends to control her powers.

Bo had possession of the Helskor.

Bo had only one focus it seems in the time after Kenzi's death and that was getting her back no matter the cost in doing so.

Apparently, Bo's dream mother would be Tina Turner.

Apparently, Bo does not have a middle name.

According to Persephone, when Bo gets angry she looks like her father.

Apparently, Bo and Tamsin shared not just food but playtoys as well.

Bo's truth was that she loves both Dyson and Lauren.

Bo's Father is Hades.

Bo believes that she is the reason why Aife is insane, that the memory of her is the trigger for Aife losing her sanity at times.

Bo has the power, apparently, to cause Fae who are mentally isolating themselves to become responsive for a short time.

Bo was the firs to discover that Hades had killed both Trick and Aife.

Bo did not receive physical gifts from Trick's will, but rather the knowledge that Trick loved her dearly and completely.

At one point in the series, Bo fell under the control of her father and created havoc in his name, but she did, eventually, break free.

When Bo fought Hades, her inner Chi and power had turned a different colour than it had been before. Instead of being blue, as it had been through the series, it turned a purplish colour.

Bo's battle with Hades came down to one difference between them. Hades did not have a good side to him, but Bo did. Bo's good side was given through the love of Trick and in having that, Bo was able to overcome Hades.

At the end of the series, Bo and Lauren were a couple with Dyson supporting their choice.
